. I b all whom it may concern Be it known that we, Ronnn'r E. -Kn.\i rER and ARTHUR KE PE citizens of the United States, residing atRensselaeI', in the county of Rensselaer and State of New York, have invented certain new andquseful Improvements in Machines'for 'Feeding Sheets and Like Articles; and we do hereby declare the following to be a full. clear, and exact de-- scription of the inventiornfsuch asayill en-' able others skilled in the art to whichlit apperteins to ma'ke and use the same.

Our-'- invention consistsin the novel fea-- tures hereinafter described, reference being had to the accompanyingdrawings which shown form or embodiment of the invention which we have selected forthe purpose of illustrating the same, and the invention is fully disclosed in the following description" and .claims. v

Referring to the said drawings, Figure 1 represents a right side elevation of the ma chineor embodiment of our invention which we have selectedfor purposes of illustration. Fig. 2 is a left side elevation of the same. Fig. 3 is a top plan view of the machine. Fig. 4 is afront elevat on thereof. Fig. 5 isa vertical'long itudinal sectional view of the machine taken on the line 5 5, Fig. 3, looking in the direction of the'arrows in that figure. the parts being shown in the positions which they occupy when. the .comber has combed forward the topmost sheets of.the. pile, the separators have'raised the .tQP nost sheet fro-1n the pile and the Z i the side frames of the machine which are that figure and showing the parts in the g positions whichthey occupy when the topmost sheet-ha's been partially fed. The object of our invent on -1s to provlde. an apparatus for automatically feeding in rapid succession sheets of {paper orother T. like articles, to a printing press or for an e h Pu po In c r yin out ur nventi'on we.;pro .vide neans for supporting thehsheets or artickstobe fed singly, n a

vertical pile without the necessity of having thesheets or other articles fanned out; mechanism is provided for combing or fanning out 'or pushing forward the topmost sheets or articles, the topmost sheet being cqmbedout farther than the adjacent sheets: separating mechanism is also provided for separating the topmostsheet from the rest of the pile and a dividing device is pro-- vlded which is moved between the separated sheet and the balance of the pile and preferably carries the sheet, into engagement with a feed roller, which is preferably a continuously moving roller and which feeds and delivers the sheet selected by the separating and dividing mechanism;.1neans a re also provided for' pushing back the upper sheets of the pile which may have been partially thrust forward when the topmostshect was combed out, so that the topmost sheet will always occupy a predetermined position at the beginning of each cycle of operation of the apparatus. Means are also provided for automatically advancing the support for the pile of sheets or other articles, so as to'maintain the topmost sheet ,ilL practically uniform relationwith the on and particularly with! respect to the conibei as we term the device for combing or forming out the top. sheet.

Referring to the particular embodiment of the-invention which -we have selected 5 for purpo:-:es pf illustration and which will i now be descrlbed in deta l, A, A represent connected by'suitable cross bars a, a to form ous parts of the mechanism.

The shaft,C is provided .at one end, see Fig. i 2, with a ratchet wheel 0' whiohis en aged 1 by .a lockingpawl .c secured to the ad aoent which is secured to m vertically disposed; rack bar B mounted in guides b, secured parts of the apparatus which operate therea rigid structure capable of supporting variside frame and also by a pawl 62 pivoted to a short arm secured to a rock shaft D mounted in 'the side frames of the machine, the said'pawl d being held in engagement with the ratchet wheel 0 by a spring (Z The rock shaft 1) just referred to carries the comber or device for fanning or combing out the topmost sheet of the pile, 4 In this nstance we have shown for this purpose a rotary disk E provided with a plurality of small idle rolls 6, the periph- I cries Of'which extend beyond the periphery' o-f'the disk. Thedisk-E is mounted on a shaft 0 which is carried at. the outer end of. aframe 6? which is r gidly secured to ,the rock shaft D.

We also provide in'eansfor elevating the comber :out1of, contact with the pile of sheets or other articles during a port-ion" of the cycle of? the machine and for'lowc'ring it into contact with the topmostsheet at the proper pointinthecycle- For this purpose we have arm d (Figs. 2, 3 and 4:) secured totherock shaft D and provided at its outer nd withfa friction roll d? which is engaged by a cam G I k I It; will be noticed that 'the arm d and on the shaftiG.

h represents'gme feed j roller wh ch' ris pile the friction roller mounted upon the shaft H,supported in the side frames above the delivery end of the table B and we also prefer to provide a delivery rolle'r it forward of the feed roller 72 and an idle roller 7L located above and in contact with the delivery roller h for taking the sheets or articles as fed by the feed roller h and delivering them from tl1e ma-. chine. The delivery roller h is mounted on a shaft H carried in the side frames and the idle roller 71 is provided with'gudge ons 70 slots .in the sidefframes or parts secured thereto, for hold-mg the idle'roller in its proper position In this instance continuous motion is transmitted to the feed roller 7'5 which engage vertically disposed guidesmr" h and the delivery roller h by means of a sprocket chain-hf which passes around a driving sprocket f on the shaft F, and an idle sprocket k secured to one of the side frames at the forward end of the machine,

.said chain passing over a sprocket h on the shaft Hi and underfa sprocket h on the stance it is shown in egral. One or more of said separators may be employed,'as de-- ortion L. In this in- .sired, and in the present instance we have shown two of the same.- Each of the'separatdrs is pivotally secured to the outer end of an arm K which is rigidly secured to a rock shaf-t'J mounted in the side frames of the. machine for the purpose of controlling the movements of both separators. Each of the separators L is normallypressed yieldingly toward the pile' 'of sheets or like articles by means of a very light spring Z suitably connected to the separator L at one end and having its other end connected to an arm. It projecting downwardly from the arm K. On account of.thedelicacy gf much whiclrthese separators must have, we

find it convenient and desirable to form the f" separator from a piece of sheet'steel or other metal in the form of,a blade, the lower end of which is bent outwardly and then upwardly .toform a short arm 1 and the pivot connect ing the separator to the outer end of the arm- K, passes through both the main body of the separat'dr and the short paralle'l'portion or arm Z thus providing an elongated bearv ing for this pivotal connections Thehpper end of the spring Z is preferably connected tothe shortarm Z-,'"as shown inFi 5 and the lower end of the spring is provi ed with a fiexibleconnection Z which is wound upon a small'drum Z secured in position onthe Losses? arm k by ascrew or bolt and by turning this drum more or less the tension of the spring can be very delicately adjusted.

' The shaft J which carries the arms K to which theseparators are connected, is provided with an actuating arm 7' having at its outer enda friction roller which engages a cam G on the shaftG, said cambeing constructed to impart the desired movement to the separator or separators. The friction roller y" is'held in engagement with the cam G by means of a spring j secured atone end to the arm 7' and at the other end to a stationary part'of the machine, in this i stance a cross bar a, see Fig. 4.

Each of the separators L is disengaged from the. sheet or like article and held normally out of engagement therewith during a portion of the cycle of the machine, by a device which we term a kick-oil, one of said devices being provided for each of the separators- Each kick-off consists of a verti c'ally disposed arm m (rigidly secured to.a

rock shaftlM mounted in the side frames of the machine) and provided at its upper exit] with a stud or pin m" for engaging the separator on therear side thereof. The rock .shaft. M is provided with an arm m extending upwardly therefrom and provided with a friction roll m which engages a cam G on the shaft- G for operating the kickofls' at the propertime. The actuating arm m is held-in engagement with the cam G? 5 by a spring and in this instance we have two being shown herein. Ea'ch of these jog:

. rigidly secured to a rock shaft mounted -i n.-the side frames and each of said arms N 1 shown for this purpose a spring m conand'at the other end to a rea-rwardly exarm m, Fig. 5, secured to the rock The operation of the comber in fanning out the topmost sheet, will ordinarily also fan put or comb out several of the uppermostsheets to a less extent, by'reason of the frictional contact between ,the' several sheets and we provide devices which we terni jogger's for the purfiose ofpushing back all of the sheets thus disturbed, except 'thetopmost sheet, whichwill be fed and delivemd as hgreinafterilescribed. One or moreT'of these Joggers. may be employed.

gers consists'ofa vertically disposed arm-N is provided at its upper end with a vertically disposed: plateportion n extending latel-ally on one or both sides of the arm, in this case on both sides as clearly shown in Fig. 4. The rock shaft is provided with an actuating arm 0 carrying at its outer end a friction roller 0..Wh1Ch engages acan -G 6n; the shaft G. The friction roller 0" is 7 held in engagement with said cam by means of a'spring, n this'instanc'e a spring a, see

,arm 0? secured to the rock shaftO. 1-.. At' the proper time in the cycle cf lthe machine, the I cam Gvpermits the spring 0 acting through the arm-o and rock shaft 0, to more thejoggers rearwardly and push hackfthe sheets at the top of the pile whichhave'been combed out at the same timeas the topmost sheet. v

We also provide'stationary' guiding de-- vices fol-engaging the front and rear edges" oft-he sheets or other articles in the pile carried by the supportingtahle B for holding the sheets o-r other articles in alin'ement upon said table. The front guides consistof verticallydisposed arms provided at their lower ends with collars p rigidly but adjustablysecured to one of the cross bars a of the machine, as clearly shown in Figs. 5 and 6; in'this instance-the collars 79 are secured to the'cross bar by a set screw 7).

The rear guide consists, of a cross bar R provided with depending guide fingers 1' engaging the rear ends of the sheets or other articles, the said cross bar being supported on horizontal rails Q, Q; secured to the side cross bar It is provided with a strap 1" extending over the top of the same and having its epdfl 4i extending downwardly outsideof the; rails the cross bar R lying between said rails," and the downwardly ex- -tendingends r of the strap are provided with set screws 7 for securing the cross bar rigidly in position with respect-to therails Obviously tlie cross bar may be ad justed to different positions on the rails, to-' ward and from the front guides P, P to accommodate sheets or, articles of: different lengths. v 7

As the sheets or articles may;.frequently be of less length than the .table or support B, said table or support is preferably made of open or slatted construction with longitudinal openings between the slats in vertical alinement with the fingers r of the rear guides, so that said fingers will not interfere with thevertical movement of the table B, as shown in the drawings, in Figs. 5 and 6 of which the fingers 'r are shown extend: ing into the ope portions of thetable.

We also proviile mechanism for positively dividing the topmost sheet after its edge has been elevated by the separator or separaters, from the balance'of the sheets in the pile and for-bringing into action a pressure roller which presses the topmmi t or separated sheet into contact with the rotating feed roller ,h. These parts need not of necessity be connectedw'ith each other; in the embodiment of-t-he invention which we have selected for purposes 'of illustration. however, we have shown them combined and comprising a dividing device having a wedge shaped portion to enter the space below the topmost sheet when the latter is raised, and carrying the pressure roller.

S represents the divider which is disposed horizontally and arranged to reciprocate.

It consists of a horizontal plate which is supported in part upon the cross rod (1 upon which it slides and in part by a vertical arm t to which it is piyotally connected at its outer or foremost end. The arm is rigidly secured to a rock shaft T mounted in the lower part of the side frames and said rock shaft is provided with an actuating arm 15' carrying at its upper end a friction roller t engaging a cam G on the shaft G, see Figs. 4c and 6. The rearward end of the divider is inadejwedgeshaped as shown at s and in rear of said wedge shaped portion a pressure roller 8 is mounted ro-,

.tatably in the divider, said pressure roller being in line withthe feed roller, hand adapted to press the separated sheet or other article into contactwith the feed roller h.

The operation of the machine is as follows: The pile of sheets or other articles to be fed by the machine is placed upon the table B with the front edges against the front-guides P, tlie table B being lowered by releasing the pawls c and d and allowing the rack bars to slide to their lowest position. The rear guide is then adjusted so as to engage the rear edges of the pile of sheets or other articles. Assuming that the machine'is in position to commence its cycle of operations and that the comber is in raised osition, the table B is then raised by hand until the topmost sheet is nearly in engagement with the comber when the machine may be started. The machine is operated' either by hand or by power but preferably power, motion being imparted in any desired way to the shaft G. Vhen the machine is in'operation, the comber will drum or fan out the uppermost sheets as indicated in Fig. 5, thetopmostsheet being fanned or combed out farther than those immediately beneath it, the front guides l f terminating at this point below the top of the pile so as not to interfere with this fanning out or combing out operation. At the same time the kick-offs are moved backward so as to permit the separators to move rearwardly until. their serrated portions Z "engage the forward edge of the topmost sheetwhich projects slightly beyond the corresponding edge of the sheet beneath it and the separators are then elevated bymeans of the spring 9' operating in conjunction with a suitable grade of the cam G thereby lifting the front edge ofthe topmost sheetin a direction toward the feed roller h as clearly shown in Fig. 5. At the same drawnrearwardly by a spring connected to the adjacent side frame A, thereby turning the rock shaft Ti and causing the arm 2? to move rearwardly together with the divider S, thus carrying the wedge shaped portion of the divider beneath the top eration continues the divider S continues to move rearwardly, the separators which have performed their functions arelowered and withdraw the separators from engagement with the sheet or article to be fed and the divider moving still farther rearwardly brings the pressure roller s1 into engagement with the sheet above it and presses the sheet against the feed roller /1. Atthe shown in Fig. (3. At the same time the joggers are operated rearwardly, their upper ends or plate portions which. as shown. extend above the front guides P, striking the pile below the selected'sheet or topmost sheet, force them back to their original po sheet which is being operated upon by the feed roller /2 and delivery roller h, from It is not necessary that the joggers should .push the topmost sheet beneath the selected gers --1". but we piefer to so adjust the ma permost sheets which have been disturbed,

as to preclude the divider passing over in- T he sheets or other articles may be dehvered to a printing press or other machine sired. v t

\Vhile we have shown' herein only one comber, and one dividing device, it is to'b c understood that we may employ two or also employ a-ny desired number of separatorsfand any desired nu'n'iber of'joggers.= \Vhile we have shown the separators so an ranged that they shall he reciprocated vertically, this is not essential to the operation f the .machine, as the action of the comber ior combers in combing out the. topmost time the cam Gr permits the arm 25' to be at one end to said arm and at the other end.
